Shutter Buttons

Shutter Buttons seal ferrule tie holes in steel or timber formwork. Contractors use them to prevent concrete from leaking through tie rod openings. This keeps the formwork clean and reusable. Joluka’s Shutter Buttons work with both traditional and European shutter systems, including PERI and DOKA. These buttons come in multiple sizes: 14mm, 16mm, 18mm, 20–25mm, 21mm, and 25mm. The Vario model fits hole diameters from 21mm to 24mm, making it ideal for aluminium or steel-framed shutters. Each button fits snugly and stays in place during casting. Joluka designs these accessories to be tough and affordable. They resist wear and tear on busy construction sites. Their plastic build ensures minimal water absorption and high chemical resistance. This makes them suitable for demanding environments. Shutter Buttons pair well with other Joluka products. Use them with Plastic Ferrule Tubing to protect expensive thru ties.
